Abstract

Anaerobic co-digestion of dairy manure and edible mushroom cultivation waste was conducted to produce biogas using batch reactor. Influence of temperature on anaerobic digestion was studied, and recovery ability of bacterial activity after second feed was also investigated. Three temperature conditions of room temperature condition (16.5 -25 ), mesophilic condition (36 ) and thermophilic condition (55 ) were chosen, and experimental result indicated that room temperature was unfit for anaerobic digestion. Anaerobic digestion under mesophilic condition and thermophilic condition proceeded well, and the latter had earlier and higher daily biogas production peak. Second feed period achieved higher biogas yields of 199 mLúg-1 VS and 222 mLúg-1 VS under mesophilic condition and thermophilic condition respectively without lag phase. Seven to ten days of lag phase existed and biogas yields were 190 mLúg-1 VS and 213 mLúg-1 VS respectively under same conditions during first feed period. These results could provide beneficial information for scaled project.
